lniGreat Britain March 2'l,* 1942 This invention relates to areel foruse in treating artificial-filaments, threads, fibres and the like,hereinafter referred to as threads, and

is particularly adapted for treating a thread with.

ainumber of different liquids in succession, while the thread is 1'carried by and isetravellingalong athread-advancing device; a w v It hasalready beeniproposed to producers. thread by extruding a thread-formingsolution such asvisco'se into a coagulating bath and'then to pass thethread as it leaves the coagulating bath into. contact, witha successionof different: treating liquids, such for instance as washing,desulphiding, bleaching, and final'washing liquids, and then to dry thethread, sothat it is, in

one continuousoperation, produced as the fin.

ished thread, ready to be employed for textile purposes. a It has beenproposed to carry out the treatment of the thread withythe differentliq-.-; uids on a succession of rollers, one roller or set of rollersbeing employed foreach operation, and each roller or set of rollersdipping into, or being sprayed with the required liquid.

It has also been proposed to pass the thread leaving the coagulatingbath on to a device or series of devices adapted to advance the threadin a large number of helical turns. Such devices may consist of a pairof rollers with inclined axes, or of one roller and a series of guidehooks, or of a single reel comprising two sets of interdigitating barmembers. When the thread travelling along the thread-advancing device istreated with a succession of difierent liquids, such as those enumeratedabove, large quantities of the treating liquids are required as only asingle thread or at the most a small bundle of. threads,

is treated on each device. In order to carry out the processeconomically it is necessary to provide means for recovering the usedliquids, and circulating them for reuse. When the treatment with eachliquid is carried out on a separate device, this is comparativelysimple, but when the thread is treated with several different i liquidson one device, the liquids are liable to-intermix and become unsuitablefor'further use in that particular zone of treatment,

It has further been proposed to treat thread travelling on athread-advancing reel with a succession of different liquids and tocollect the liquids separately by providing suitable means which allowthe liquids to drop off into separate collecting compartments. Forexample, the bars of the reel may be provided with ribs on the outerface of the bar so that liquid running down the holes may be provided onthe "outer face of the' bars; or; an air jet may be employed. g Ihave'now found'that I can treat'a travelling thread with a succession ofdifferent liquids and 5 collect the liquidsseparately' -by=using a reelconsisting 'of a plurality of longitudinal bar-members flttingintoslotsin a number of spaced solid discs mounted on a shaft, saidbarmembers being grooved" along most'of their lengthexceptm at thosepointswhere the bar members fit into theslotsin the solid discs;

The thread may be made to travel along the reel his large number ofadvancing helical turns by any of the well known methods. For example,two reels may *beused with their axes inclined at a slightangle, or onereel may be'used" inconiunction with a seriesoi. guide hooks, or

a' single reel may be used comprising two sets of interdigitating barvmembers with a slight: Q modification of the discs supporting the barmembers, to allow for the reciprocating movement of the bars.

The solid discs are preferably flat and circular and are provided roundtheir circumference with 25 a plurality of slots which may be taperedand are ly liquid impervious. barrier, so that the reel is divided intoa number of zones and-a different treating liquid may be applied tysprinkling to each zone, the liquids remain separate and can becollected in suitable devices placed beneath each zone. The length ofeach zone is defined by the length between two successive discs. In

the treatment of a freshly spun viscose thread, for example, a reel maybe used made from lonaigitudinal bar members according to the present 60phiding liquor in the second, followed by water in the third, ableaching solution in the fourth, and a final washingwater in the fifthzone. In this way the thread is washed, desulphided and bleached in acontinuous operation. The washbar is caused to drop oil on reaching theribs; or ll s liq i d s phidins liq and bleaching 0- lution arerecovered and circulated in any desired and suitable manner,

The drawing accompanying this specification, will assist in illustratingthe nature of this invention, but the invention is not restricted to the'method and apparatus shown in the drawing.

The drawing shows-- In Figurel an elevation of a reel according to thisinvention;

In Figure 2 an end view of the reel of Figure 1.

- 11; Figures 3 and 4 sections of the bar member at different points andIn Figure 5 a perspective view of'part of a bar member and part of adisc. 7 The reel consists of a shaft A,.capable .oi' being rotated bymeans not shown, on which, are mounteda number of circular discs Bprovided with hubs C by which they are keyed to the shaft A in anyconvenient manner.

The discs. B are provided with a number of peripheral slots D for thereception of longitudinal bar members E.

Between the discsB the bar members am provided with a groove in theirouter surface, but the portions ofthe bar members E immedi-j atelyadjacent the periphery of the discs B are not grooved. This is clearlyshown in Figure 5.

Thus at any point between the. discs B, the ,bar'

members E have a cross section as shown in Fig-" ure 3,- whereasimmediately adjacent the discs B the bar-members have a cross section asshown in Figure '4.

If a thread is caused to travel in ahelix along thereel shown inFigure 1it may be subjected totreatment with two different liquids by .ar-

ranging suitable spraying means above the reel to'the left and the-rightof themiddlerdisc B, and the treatment liquids may be collectedseparately byarranging troughs beneath the reel 7 It is thus possible tocollect the treatment liquids separately without any substantial mixingwith adjacent treatment liquids.

'The bar members E are of such a thickness that they project slightlybeyond the periphery v of the discsB as may be seen from Figures 2 and5.v It is therefore impossible for the thread to foul the periphery ofthe discs B as it moves along the bar members E.

What I claim is: 1.7 A, reel suitable for treating a travelling threadwith a succession of different liquids and collecting the liquidsseparately comprising a shaft, a plurality of solid discs mounted inspaced relationship on said shaft, a plurality of peripheral slots ineach of said discs a plurality of iongitudinal bar-members fitting insaidslots and adapted to support the travelling thread, the portions ofsaid bar-members between each two successive discs constituting a zoneof liquid treatment, andlongitudinal grooves in said bar-members,saidgrooves not extending beyond the ends of said zones of liquid treatmentwhereby treatmerit. liquid :in said grooves is prevented from passingfrom one zone of liquid treatment to next.

2. A reel according to claim solid discs are circular.
